Daniel Ploeger > Winter in Z. (2009)

During my stay at STEIM from February 3rd until February 9th 2009, I realized the multimedia installation Winter in Z. STEIM staff supported the technical realization of the installation and provided artistic feedback on the project. In addition to working on this installation, I attended workshops and lectures during which aesthetic concepts of human interaction interfaces were discussed and software and hardware developed by STEIM was demonstrated.

Winter in Z. (2009)

[P]eople should be more aware of the distinction between technological devices themselves and their virtual content. They should be aware of technology as a simple object, as the furniture of everyday life.

Daniël Ploeger grew up in the Dutch countryside province of Zeeland. Until the end of the 1980s, there were only three TV channels, but on cloudy days one could sometimes receive distorted television signals from the other side of the North Sea…




-Small black and white television with its loudspeaker cut out.

-Television loudspeaker attached to a pendulum hanging from ceiling.

-Second loudspeaker attached to the wall behind the chair (hidden).



under the table:

-DVD player


-MacBook running Max/MSP

-Make Controller connected to a pressure sensor (on chair) and a PIR motion sensor (on ceiling)

-Presonus Firebox sound card
The television shows a distorted Test Card. This test card used to be broadcast on BBC 1 when no programmes where on. The loudspeaker on the pendulum emits the 1000Hz test tone belonging to the test card. When the beholder sits down, s/he may choose to either bring the pendulum into motion or to let it be static. When the pendulum is moving, the beholder will hear sound changes caused by the movement (Doppler effect and phase differences with room reflections). When the pendulum is static, the computer program will start to simulate these sound changes using an algorithm for the simulation of moving loudspeakers in the median plane. This algorithm was developed by Daniël Ploeger in the Laboratory of Acoustics at the Helsinki University of Technology in 2008. In addition to amplitude and pitch changes, the algorithm generates phase differences between two loudspeakers (in this case the television loudspeaker and the second loudspeaker behind the beholder) according to a pre-recorded site-specific phasing pattern.
